First of all how do you guys decide what to charge for mowing, i've been just pulling a price out my head, and comparing the yards i mow now, but people are wanting me to mow bigger yards and i don't know what to charge.<p>next, i've got a home built trailor it's a 6x9 (farmer built special) it's got 15&quot; tires and the axle is a straight axle off an old 4x2 truck, the damn thing bounces all over the place, the tires on it are pretty wide, i just wondered if you guys had any ideas how to fix it. (it also doesn't have any springs, that's what i think the problem is)
